Polymer-based 3D microcones for application in SERS

This contribution presents special polymer-based 3D structures that were prepared via dip in laser lithography using Nanoscribe Photonic Professional 3D lithography system. As 3D structures, three different arrangements of microcones were performed: microcone decorated with in-line protrusions with two different periods (400 nm and 1 μm), and microcone with protrusions arranged in spiral. After that, 10 nm of Ag was evaporated onto the prepared samples. The micro-Raman measurements for Rhodamine 6G as a probe molecule show usability of metal-coated IP-Dip structures for surface-enhanced Raman spectroscopy.
